Your Favorite RPG Supplement, for any Game, Period

[wmasters]

The Dark Sun campaign setting for AD&D

 

[gribble]

I'll get in before someone else says it:

Planescape - it made D&D (well, in those days AD&D) interesting again

 

[Shemeska]

2e Faces of Evil: The Fiends.

 

[JVisgaitis]

Skill and Powers and Combat and Tactics for 2nd Edition. People gripe it was ridiculously overpowered (and it was), but I love the options in class/race building. Great stuff.

 

[Tinner]

Universal Brotherhood for Shadowrun.
Creative layout and presentation. Awesome plot twists. Great suspense.

I'd also give a nod to Hunter the Reckoning: The Walking Dead for many of the same reasons.

 

[Numion]

A really disturbing cult that practices self-castration? Check.

Are there any non-disturbing cults that do .. um, that?

My favourite supplement ever is the 3.0E Forgotten Realms Campaign Setting. Great amount of stuff crammed into a beautiful package. I'm hoping Ptolus will top that, though.

 

[Particle_Man]

Complete Arcane. Because I love the Warlock that much.

 

[reanjr]

Dark*Matter campaign setting for the Alternity game.

I'll second that. I ran a Greyhawk-Planescape game for probably 10 years and it was definitely the most fun I've had playing D&D.

That's a very tough question.

I'd have to go with the 1E DMG.

(Though Planescape is right up there.)
